Chambless, Chicago, Ill. Application July 5, 1934, Serial No. 733,743 ' 6 Claims. The present invention relates generally to closures for bottles and like receptacles, and is particularly concerned with the provision of a new and improved form of ?anged or headed stopper.5 As ordinarily formed, stoppers of the type with which my present invention is concerned are formed of cork or other compressible material. Where the ?anged or headed portion is formed as an integral part of a cork stopper it has been 10 necessary to start with a relatively large cork having a diameter at least as large as the head desired and to grind the cork down to the desired (01. 215-48) of the stopper, and at the s‘ame‘time be effectively and securely restrained against pulling out and against turning along the curvature of the slit in the manipulation of the’stopper after the cork is applied. _ ‘ _ _ p 5 ' The anchoring prong or prongs'may, within the scope of the present invention, be formed in tegral with the ?ange or head forming cap or may be made separately and applied, as will here inafter more fully appear. ' Further features and advantages and a con 10‘ crete understanding of the present invention will size below the headed portion. As a result, considerable of the body of the cork has been lost, 15 and the grinding which must be done with a stone be more apparent from the following detailed de scription taken in connection with the accom panying drawing, in which: ‘ ' is slow. To avoid these disadvantages, it has‘ been proposed to attach to a cork of the desired size a ?anged or head portion, usually of '- wood, and 20 provided with a lug cemented in a socket in the body of the cork, butthis has not been suit- Figure 1 is a perspective view showing a stopper cap piece provided with a pair of toothed anchor ing studs or prongs, embodying my invention; Figures 2 and 3 are side and endviews, respec tively, of a stopper cap piece having toothed 20 anchoring prongs, illustrating a modi?ed form of able because of the Weakness of the connection between the ?anged or headed part and the body of the cork.

' v ' ' ' Y ' e' " > ' I Figure 6 shows the ?at ‘stock from ‘which the 30 My invention aims to provide a ?anged or headed stopper which is less expensive than the corks or stoppers with integral ?anged or headed portions of the same material as the body of the 35 cork, and a ?anged or headed stopper in which the ?anged or vheaded portion is attached in a better and more secure manner than heretofore. ' Another object is the provision of an improved head or ?ange forming cap and improved anchor- 40 ing means for securing the same to the body of the cork. I ' ' " ~ ' ' Another object is to provide an improved meth0d of securing the cap to the bodyiof the stopper which contemplates, ?rst, forming a suitable slit in 45 the body of the stopper, and then securing the anchoring prongs of Figure 4 areyformed; Figures 7 and 8 are a perspective view and an underneath view, respectively, of the cap piece or ferrule section provided with slits in the body por tion thereof to receive ‘the anchoring means 35, shown in Figure 4; ' ' " U ' ' _ ” ‘ > Figures 9 and 10 are “an elevation'view and a plan view, respectively, of a'cap piece‘illustrating a third modi?ed form of 'my invention; ‘ ' r Figure 11 shows a tool in the operation there'- 40. of for cutting a circular ‘slit in the central por__ tion of the stopper body ‘to receive the anchoring prongs of the cap piece; 1 3 ' ‘I Figure 12 is a‘plan View of a blankfrom which the anchoring means is formed, illustrating a 45' cap thereto by forcing the anchoring means into the body portion and into the slit cut therein. Another and more speci?c object is to provide fourth modi?ed form "of my invention‘; and Figure 13 is a central vertical sectional view through ‘the anchoring means of Figure 12 and anchoring means in the form of a thin prong, or a a cap appliedthereto. ' ' ' _ - ‘ :1 1 ' 50 plurality of thin prongs having curved central portions conforming to the curvature of the slit formed in the body of the cork and serrated edges Referring now more'particularly to Figure 1,‘ 50 the cap piece, which is adapted to'be mounted on a cork or stopper, is preferably formed‘ of of ?sh-hook form disposed out of the direction of curvature of the curved central portions so that 55- the prong or prongs will readily enter the body sheet metal or other suitable material, and com prises a ferrule section I "having a ?ange v2 and ‘a central section 3 adapted to go over the‘ end of 55; 2 > 2,130,081 a stopper, preferably one formed of a compressible material such as cork. In the form of the inven tion shown in Figure l, the stock from which the ?anged cap I is made is provided with extended sections, preferably integral with the portion of the stock from which the ?ange 2 is formed. These extensions, when formed, are provided with a pair of prongs ‘I and 8 connected integrally with the ?ange 2 by angularly disposed sections l0 10 and | | formed to lie against the central section 3 and the ?ange 2, as shown in Figure 1', the prongs being resilient. The anchoring prongs ‘I and 8 are of especial importance in the present invention. Each of 15 these prongs is formed with a central arcuate and axially extending portion |5 having laterally di rected teeth H on each side, slightly curved reversely to the curvature of portion l5. These teeth are preferably cut so that they are of gen 20 erally ?sh-hook formation. That is to say,’ the ends thereof are directed laterally and also in a direction towad the cap piece I. By virtue of this formation, whenever the cap‘ piece I with the prongs '| and 8 is applied to a cork and the 25 prongs forced into the material of the body por tion of the cork or_stopper, the teeth |'| facilitate entry of the prongs and, at the same time, effec tively bite into the body of the cork or» stopper so as not only to prevent the withdrawal of the 30: cap piece from the stopper but also to prevent the rotation of the cap piece relative to the stopper, the prongs twisting slightly so as to increase the conical, it is to be understood that it could be cylindrical or any other desired or necessary shape. The cap piece is indicated in Figures 4, 7 and 8 by the reference numeral 4| and includes a central section 42 and a ?anged portion 43. In this case the cap piece 4| has its central sec tion 42 formed with a pair of slits 44 and 45, each central portion of which is curved and each having end portions disposed at an angle thereto. A U-shaped anchoring stud is employed with 10 the cap piece 4| and is indicated in its entirety by_the reference numeral 50. The anchoring stud means 50, shown in Figures 4 to 8, is a part separate from the cap piece proper, whereas in Figures 1 to 3, the anchoring stud means is formed 15 integrally therewith. In Figure 4 the central portion 5| of the anchoring stud means 50 is shown as embracing the portion 53 of the cap piece 4| between the slits 44 and 45 in such a manner that the prong sections 55 and 56 extend 20 in an axial direction relative to the cap piece 4| and the stopper 40. The prong sections 55 and 56 are preferably of the same construction as the prongs ‘I and 8 shown in Figure 1; that is, each prong is provided with a central axially extend 25 ing curved section 51 and reversely curved later ally fiaring tooth portions 6|] of ?sh-hook forma tion. It will be observed that the end portions of the slits 44 and 45 are of approximately the same angularity as the teeth 60 on the anchoring prongs 55 and 56. This facilitates the insertion of the anchoring member 50 in the slits 44 and 45. Figure 6 illustrates the stock, partly processed, grip of the teeth. While I have shown two prongs ‘l and 8, it will r be apparent that the present invention could be from which the anchoring studs 50 are formed, and it will be noted that the flat stock is formed embodied in‘a cap piece having only a single with the teeth 60 extending generally inwardly anchoring prong. toward thecentral portion 5|a of the piece of stock, the central portion 5|a being rounded to And the prong or prongs may be integral with or separate from the cap part. The cap piece and the attached anchoring 40, prongs shown in Figures 27 and 3 are of a con cover the intermediate section 53 mentioned above. 40 Figures 9 and 10 show a fourth form of the struction quite similar to that shown in Figure 1 with the exception that a smaller amount of invention. This form differs from the previously stock is required and the anchoring prongs are described forms in one important respect. In ?at and do not have any curved sections. Re Figures 9 and 10 the cap piece includes a ?anged ferring now to Figures 2 and 3, the cap piece cover section 65 the central portion of which is is indicated in- its entirety by the reference provided with four arcuate slits to receive tongues numeral 20 and comprises a ?at central section 66, 61, 68 and 69 formed on a cylindrical anchor 2| slit at 22 and 23 to form a pair of flat gen ing stud 10. The stud 10, like the anchoring erally axially extending anchoring prongs 25 and prongs described above, formsthe means for se-, 26. The prongs 25 and 26 are provided with curing the cap piece 65 to a stopper or the like, 50" teeth 21 of ?sh-hook formation and soinclined' but the anchoring member 16 is not provided with that the insertion of the prongs into the ma teeth as such. Rather, the cylindrical anchoring terial of thestopper is facilitated while the with member 10 is provided with a number of openings drawal of the cap piece from the stopper is effec 12. These openings, however, like the teeth de scribed above, generically speaking, are in ,the I . 551 tively prevented. In the construction shown in Figures 2 and 3, form of cutaway portions and it has been found the prong sections 25 and 26 are formed integral that the openings 12 also effectively lock the cap piece 65 to the stopper when the anchoring-pin with the material of which the central section 2| is formed, and the prongs 25 and 26 are attached or stud 10 is forced into the material of the stopper. The tongues 66 to 69 serve to secure 60. 60 to the central section at their base portions. This particular way of punching out the prongs the anchoring stud to the central portion of the 25 and 26 leaves openings 30 and 3| in the cover cap piece 65. or central section 2|, and likewise the ?anged In the modified form shown in Figures 12 and section of the cap piece 2|) is formed in two parts 13, the anchoring means is ?rst cut in the form 35 and 36 separated a short distance as at 31 and of the blank of Figure 12. This blank comprises 65 38. While this construction leaves certain por two approximately semi-circular elements 13 con tions of the stopper exposed, it is of somewhat nected by a web element 14 from the opposite simpler and less expensive construction as com sides of which extend prongs 15, each serrated pared with the form shown in Figure 1. ’ along its lateral edges at 11. The serrations or Figures 4 to 8, inclusive, show a third form of teeth 11 of prongs 15 are shaped similarly to the ‘a stopper cap which is similar to the previously teeth ll of prongs ‘|—6 of Figure 1. The blank described forms in that a pair of anchoring is then shaped in a'suitable manner so that the prongs are provided. ,- In Figure 4, the stopper, prongs 15 extend downward from web element preferably cork, is indicated by the reference 14, substantially perpendicular thereto, this web numeral 40, and while the stopper-40 is shown as element and the elements 13 remaining ?at and 3 2,130,081 de?ning a circular head or disc at the upper ends of the prongs. During the shaping of the blank, the prongs 15 are curved transversely so as to be of arcuate cross-section, and the teeth ‘I’! are curved reversely to the prongs, in the same man ner as in Figure 1. A cap 18 is then secured to the disc at the upper ends of the prongs in a suitable manner, as by means of a bead 19 formed at the lower edge of the cap and tightly clamped 10 over the edge portion of the disc, as in Figure 13. If desired, this bead may be welded or otherwise suitably secured to the disc to prevent relative movement between the parts. With the exception of the form shown in Fig forms in which my invention has been embodied, it will be apparent to those skilled in the art that my invention is not to be limited to the speci?c details shown and described, but that, in fact, widely different means may be employed in the practice of the broader aspects of my invention. What I claim, therefore, and desire to secure by Letters Patent is: g 1. A stopper comprising a body of compressi ble material and a cap having a thin anchor pro 10 jecting therefrom, said anchor having a curved central portion and serrated edges disposed out of the direction of curvature of said curved cen suitable tool 80, shown in Figure 11, is used. This tral portion and adapted for anchoring the cap to the body of the stopper, said anchor being 15 resilient. 2. A stopper for bottles and the like compris ing a body of compressible material having an arcuately shaped slit formed in the central por tion thereof, a stopper cap disposed on said 20 body, and an anchoring prong carried by said cap adjacent the central portion thereof and hav ing a central curved section corresponding to the curvature of said arcuate slit, and outwardly 25 tool includes a head 8! carrying a tubular section ?aring toothed edges disposed outside of said 25 82, the end opposite the head 8| having a cutting curved section so that when the stud is forced into said arcuate slit the toothed edges bite into and secure the cap on said stopper body. 3. A bottle stopper comprising a body por tion, a cap piece mounted thereon, and an 30 15 ures 2 and 3, all of the anchoring means de scribed above is in the form of, or includes por tions which serve as, arcuate or curved sections. According to the preferred form of the invention, the stopper body, usually cork, which receives 20 the stopper caps of Figures 1 to 12, is preferably formed with an arcuate or circular slit for the purpose of facilitating the insertion of the an choring prongs or stud means. To this end, a edge 83. The cutting tool is rotated as it is forced downwardly into the stopper 1&0 to the position shown in Figure 11, and cuts a circular slit in the 30 central portion of the stopper, the curvature of this slit preferably corresponding to the curva ture of the prong sections. Cutting the cork in arcuate anchoring stud carried by said cap piece and having serrated edges disposed out of the this manner facilitates the attachment of the direction of the arcuate part of the stud so that cap piece and the anchoring means which it carries. The cutaway sections or portions of the anchoring means cooperate with the material of the stopper 4!] effectively to lock the cap piece thereto, both against axial displacement and rel ative rotation. When the stopper is forced into when the stud is forced into said body portion the cap piece is secured against separation from and 35 against turning with respect to said body por tion. 4. A cap for bottle stoppers and the like hav ing a thin anchor projecting therefrom, said an 40 the neck of a bottle, or like container, it is com pressed, such compression of the stopper render ing the attaching means even more effective by forcing the material of the stopper into tight contact with the anchoring means and between 45 the teeth or into the openings thereof. This is particularly true when the stopper is formed of cork or like highly compressible material. A closure made in this manner can be applied and removed a great number of times without destroy ing or reducing its efficiency. 50 When anchoring means having prongs or non arcuate or ?at cross-section are employed, the stopper is cut by suitable means to provide there in non-circular slots corresponding to the shape of the prongs. It will be understood that the 55 prongs of anchoring means may be variously shaped and disposed, and that the stopper may be cut or slotted accordingly. While I have shown the anchoring means as 60 being initially formed integrally with the cap, in certain forms of my invention, it will be under stood that, if desired, the anchoring means may be ?rst formed separately from the cap and then secured thereto by welding or equivalent means. This is an obvious variation, and need not be il 05 lustrated nor described in detail. While I have described above the preferred chor having a curved central portion and a ser rated edge disposed out of the direction of curva ture of said curved central portion. 5. A bottle stopper comprising a cap mem ber, a body member of compressible material hav ing a generally centrally disposed circular slit 40 therein, and an anchor member of a curvature adapted to ?t said circular slit, said anchor mem ber comprising a prong pressed into said slit to secure said cap and body member together and provided with serrated edges for securing said prong in said slit, said serrated edges being dis posed out of the direction of curvature of said slit. 6. A bottle stopper comprising a cap member, a body member of compressible cork-like mate rial having a curved slit within the periphery thereof, and a curved anchor member secured to the central part of said cap member and having an anchoring section disposed in said slit and provided with anchoring serrations along its 60 opposite edges, said anchoring serrations be ing disposed out of the path of curvature of the slit and said anchor member being of less than complete annular form and securing said cap member and body member together. 65 JOSEPH W.
